CN100425567C - Super white ceramic tile - Google Patents

Abstract

The invention relates to ultrawhite ceramic tiles wherein the blanks of the tiles are prepared from the following raw materials (by weight portions): clay 25-65 parts, stone fluxing agent 5-20 parts, soil fluxing agent 30-60 parts, siliceous sand 0-15 parts. Compared with the prior arts, The invention has the advantages of higher whiteness, low cost, better mechanical property and environmental protection.

Description

A kind of super white ceramic tile

Technical field

The present invention relates to ceramic tile, relate in particular to a kind of super white ceramic tile.

Background technology

Existing ceramic tile is many to be main material production with clay, feldspar and a large amount of additives that brightens.This way is not only wasted expensive resources in a large number, also used much the additive that brightens that human body and environment is had pollution, not only destroy environment, also HUMAN HEALTH is caused very big harm, and this type of formulation cost is very high, so at present along with social development and growth in the living standard, people more and more favor green health and product attractive in appearance.

Summary of the invention

Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of cost is low, satisfactory mechanical property, super white ceramic tile that the feature of environmental protection is good.

Purpose of the present invention can be achieved through the following technical solutions:

A kind of super white ceramic tile is characterized in that, the base substrate of this ceramic tile is made by following raw materials in weight portion:

Clay 25-65 part,

Stone matter flux 5-20 part,

Soil property flux 30-60 part,

Silica sand 0-15 part.

The base substrate of described ceramic tile can also be made by following raw materials in weight portion:

Clay 30-50,

Stone matter flux 5-10,

Soil property flux 40-60,

Silica sand 0-10.

Described clay is grey loess and/or white clay, described stone matter flux is selected from and comprises potassium albite, celsian-felspar, albite, potassium felspar sand, nepheline, contains in the lithium minerals one or more, described soil property flux is selected from and comprises in lime feldspar, calcite, rhombspar, the talcum one or more, and described silica sand is SiO ₂Silica sand.

The base substrate of described ceramic tile is made of the chemical constitution of following quality proportioning:

Aluminum oxide 10-30 part,

Silicon oxide 50-65 part,

Ferric oxide 0-0.5 part,

Titanium oxide 0-0.1 part,

Calcium oxide and magnesium oxide 10-20 part.

The present invention can produce the high-grade brick that whiteness is fine and quality is soft not using fully under the expensive situation that brightens additive by using some whiter and soil property flux that price comparison is low, stone matter flux and silica sands.But there is a technology prejudice in the traditional concept of ceramic industry, thinks and can not use too much flux in the blank raw material of ceramic tile, otherwise can make the firing range product distortion that narrows down.

The present invention has introduced white soil property flux in the blank of ceramic tile, brighten additive thereby can not re-use.Not only save cost, protection environment and human body health, and also because other proportioning raw materials and technology controlling and process are proper, so not distortion of the product of producing, inner quality is good, and can reduce cost more than 30%.The product performance folding strength reaches more than the 36Mpa, and the product water-intake rate is≤0.05%, and whiteness is 80～91.

Embodiment

Below in conjunction with specific embodiment, the invention will be further described.

Embodiment 1～5

The embodiment 1～5 of super white ceramic tile of the present invention (unit of blank component is %) is as shown in the table:

Above-mentioned super white ceramic tile manufacture method is: by weight ratio composition batching, and---ball milling---detects that---blowing---sieves and---stirs that------old---------printing---burns till that---polishing (or selection)---selection---is packed to drying to spraying drying to press brick (or decorative pattern, particle, pit etc.).
